Definitions
- the present invention relates to an ink-jet recording apparatus.
- ink-jet recording apparatuses of a serial type printing is carried out by placing an ink-jet head on a carriage and moving it reciprocally in the printing width direction of the recording medium.
- a maintenance unit for conducting maintenance of the ink-jet head is disposed in a location beyond the printing area of the ink-jet head.
- the ink-jet head In a non-driven state, the ink-jet head is positioned facing the maintenance unit and the ink nozzle surface is capped with a cap to prevent foreign matter from adhering to the nozzle surface. Further, the thickened ink and gas bubbles admixed to the ink are removed by conducting ink discharge or ink suction through the nozzle in a capped state.
- Such maintenance units were the object of various improvements aimed at miniaturization (for example, Japanese Patent Application Laid-open No. 2003-94674) or creating a replaceable configuration (for example, Japanese Patent Application Laid-open No. 2000-203044).
- Such maintenance units are usually attached with screws and the like to the apparatus body.
- accurate positioning is required. Therefore, a high installation accuracy is required when the maintenance unit is attached or replaced.
- the present invention was created to resolve the above-described problems and it is an object thereof to enable accurate positioning of an ink-jet head facing a maintenance unit even if the maintenance unit has not been attached with a high installation accuracy.
